condense string function: how to remove gaps?

[jrgkraus]

I am trying hard to use the condense string function to strip space from a string. This is my coding:

  cl_demo_output=>display( condense(
    val = 'a b'
    from = ' ' to = ``
    ) ).

But the output is

How can I get the good old condense ... no-gaps with this function?

The only thing you need to change is from value, like this:

DATA(result) = condense( val = ` abc def ` from = ` ` to = `` ).
